Cytopathology of myeloid sarcoma: a study of 16 cases

The diagnosis of MS in cytology specimens can be made in cases with adequate cellularity and supportive ancillary studies in the correct clinical context. MS was harder to diagnose in cytology cases with low cellularity, blood contamination, and few blasts. Cytologic features that pose diagnostic pitfalls are lymphoglandular bodies suggestive of lymphoma and maturing or mixed granulocytes that mimic infection.
